Power Grounding Condition

1.4.1 Usage of J61 Connector Pin and its application

(1) Usage of J61 Connector Pin

For N300 Inverter, a protection circuit is built-in case of lightning while being used, and it can be also protected when J61 Connector Pin is connected

However, the Inverter can be seriously affected according to its grounding condition(grounding

or non-grounding) of input transformer

As a result, when Inverter products are yielded, J61 Connector Pin is separately provided (open condition) Users should choose a set of J61 Connector Pin according to the second grounding condition of input power as the below picture after deep consideration of your field situation

(2) Comparison according to J61 Connector Pin Using or Non-using

a) Advantage of using J61 Connector Pin

Electronic products are often damaged by lightning or thunderbolt due to its sensitivity for the weather changing For N300 Inverter, a protection circuit is built-in to protect the inverter from lightning or thunderbolt by using J61 Connector Pin

Pre-caution

You should confirm the grounding condition of power source

When using the second inverter(inverter power input), you should confirm if Y wiring is in neutral ground system and if wiring is in upper ground system If you use J61 Connector Pin in non-grounding system, Inverter can be easily damaged by excessive noise from being

Location of J61

Trang 22

c) 30KW ~ 132KW Inverter Capacity (the same location as 200V Supply & 400V Supply)

(2) Application Method of J61 Connector

Sequencing of Application

You should turn off the power, after halting Inverter working

You should open the Inverter cover located in the bottom level At this very moment, you should use Meta and confirm if DC voltage between P and N is completely discharged

As J61 is in a different location according to Inverter capacity, you should confirm if J61 is in the right location For J61 Connector Pin, 5.5KW~22KW Inverter capacity is located in the bottom right of IGBT PCB and 30KW~132KW Inverter capacity is in the bottom right of Ro-To PCB After checking out its location, you should connect Jump line(ending line) to J61 connector You should close the bottom cover after application

You should operate the machine after turning on the Inverter power

(3) Important items when applying J61 Connector Pin

Trang 24

2.1.1 Installation

1 Transportation

This inverter has plastic parts So handle with care

Do not over tighten the wall mounting fixings as the mountings may crack, causing is a risk of falling

Do not install or operate the inverter if there appears to be damage or parts missing

2 Surface for Mounting of Inverter

The temperature of the Inverter heatsink can become very high (the highest being about 150 ) The surface, which you are mounting the Inverter onto, must be made of a non-flammable material (i.e steel) due to the possible risk of fire Attention should also be mabe to the air gap surrounding the Inverter Especially when there is a heat source such as a breaking resistor or reactor

3 Operating Environment-Ambient Temperature

The ambient temperature surrounding the Inverter should not exceed the allowable temperature range (-10 to 50 )

The temperature should be measured in the air gap surrounding the Inverter, shown in the diagram above If the temperature exceeds the allowable temperature, the component life will become shortened especially in the case of the Capacitors

(Note1) 10cm or more for 5.5 to 75kW 30cm or more for 90 to 160kW (Note2) 10cm or more for 5.5 to 75kW 30cm or more for 90 to 160kW But for exchanging the DC bus capacitor, take a distance 10cm or more for 5.5 to 15kW 22cm or more for 18.5 to 75kW 30cm or more for 90 to 160kW

Trang 25

7 Ventilation within an Enclosure

If you are installing one or more Inverters in an enclosure a ventilation fan should be installed Below is a guide to the positioning of the fan to take the airflow into consideration The positioning

of Inverter, cooling fans and air intake is very important If these positions are wrong, airflow around the Inverter decreases and the temperature surrounding the Inverter will rise So please make sure that the temperature around is within the limit of the allowable range

8 External cooling of Inverter

It is possible to install the inverter so that the heatsink is out of the back of the enclosure

This method has two advantages, cooling of the inverter is greatly increased and the size of the enclosure will be smaller

To install it with the heatsink out of the enclosure, a metal fitting option is required to ensure heat transfer Do not install in a place where water oil mist flour and dust etc can come in contact with the inverter as there are cooling fans fitted to the heatsink

A final check should always be made with a voltage meter

After removing the power supply, there is a time delay before the capacitors will dissipate charge

1 Main power terminals (R, S, T)

Connect the main power terminals (R, S and T) to the power supply through a electromagnetic contactor or an earth-leakage breaker

We recommend connecting the electromagnetic contactor to the main power terminals

Because when the protective function of inverter operates, it isolates the powers supply and prevent the spread of damages and accidents

This unit is for three-phase power supply It isn't for the single-phase power supply If you require a single phase power supply unit, please contact us

Don't operate with on/off of the switch set up in the converter side and the inverter side Do an operation stop by the operation order (FW / RV) terminals

This inverter becomes the following condition at the time of open phase because open phase ction is being made ineffective by the early data

R phase or T phase, open phase condition: The power isn't turned on, and it doesn't operate

S phase, open phase condition: It becomes single-phase operation condition Trip operation such as

a deficiency voltage or over current may be done Don't use it under open phase condition

A converter module may be damaged in the case shown below Be careful

When an unbalance of the power supply voltage is more than 3%

Power supply capacity, 10 times of the capacity of inverter and case beyond 500kVA

When a change in the rapid power supply voltage occur

(Example) When inverter of the plural is installed with the common electric wire whose it is short by each other When there is insertion of the condenser or a removal

On/off of the power supply isn't to do it more than three times in one minute

It has the possibility that inverter is damaged

2 Inverter output terminals (U, V, and W)

Wire with thicker wire than the applicable wire to control the voltage drop

Particularly when outputting low frequencies, the torque of the motor will reduce by the voltage drop of the wire

Do not install power factor correction capacitors or a surge absorber to the output

The inverter will trip or sustain damage to the capacitors or the surge absorber

In the case of the cable length being more than 20 meters, it is possible that a surge voltage will be generated and damage to the motor is caused by the floating capacity or the inductance in the wire (400V especially) An EMC Mains Filter is available, please contact us

In the case of two or more motors, install a thermal relay to each motor

Make the RC value of the thermal relay the value of 1.1 times of motor rated electric current

Install output ACL when a life becomes short by the length of wiring

3 Direct current reactor (DCL) connection terminals (PD, P)

These are the terminals to connect the current reactor DCL (Option) to help improve the power factor.The short bar is connected to the terminals when shipped from the factory, if you are to connect a DCL you will need to disconnect the short bar first

When you dont' use a DCL, don't disconnect the short bar

4 External braking resistor connection terminals (P, RB)

The regenerative braking circuit (BRD) is built-in as standard up to the 15kW Inverter

When braking is required, install an external-braking resistor to these terminals

The cable length should be less than 5 meters, and twist the two connecting wires to reduce

inductance

Don't connect any other device other than the external braking resistor to these terminals

When installing an external braking resistor make sure that the resistance is correctly rated to limit the current drawn through the BRD

5 Regenerative breaking unit connection terminals (P, N)

The Inverters rated more than 18.5kW don't contain a BRD circuit If regenerative braking is required

an external BRD circuit (Option) is required along with the resistor (Option)

Connect external regenerative braking unit terminals (P, N) to terminals (P, N) on the inverter

The braking resistor is then wired into the External Braking unit and not directly to the Inverter

The cable length should be less than 5 meters, and twist the two connecting wires to reduce

inductance

6 Earth (G )

Make sure that you securely ground the Inverter and motor for prevention of electric shock

The inverter and motor must be connected to an appropriate safety earth and follow the local

standard Failure to do so constitutes an electrical shock hazard

(2) Wiring of main circuit terminals

The wiring of main circuit terminals for inverter is the following picture

Trang 34

Refer to "(4) Common applicable tools"

(Note1) The applicable tools indicate for Hyundai standard four-pole squirrel-cage Motor(Note2) Select applicable tools for breakers examining the capacity of breakers

(Use Inverter type.)(Note3) Use earth-leakage breakers (MCCB) for safety

(Note4) Use 60/75 copper electric wire

(Note5) It needs bigger wires for power lines, if the distance exceeds 20m

2

(Note6) Use 0.75mm for Alarm output contact

(Note7) Separate by the sum wiring distance from Inverter to power supply, from inverter

to motor for the sensitive current of leak breaker (MCCB)

(Note8) When using CV wire and wiring by rigid metal conduit, leak flows

(Note9) IV wire is high dielectric constant So the current increase 8 times

Therefore, use the sensitive current 8 times as large as that of the left list

And if the distance of wire is over 100m, use CV wire

Wiring distance Sensitive Current (mA)

It also improves the power factor.

Using the the inverter may cause noise on the peripheral radio through the power lines This part reduces noise.

This part reduces common noise generated between the power supply and ground, as well as normal noise Put it in the primary side of inverter.

This part reduces radiation noise emitted from wire at the input This part control harmonic from inverter.

This part is used for applications that need to increase the brake torque of the inverter or to frequently turn on and off and to run high inertia load.

This part reduces radiation noise emitted from wire by setting between inverter and motor And it reduces wave fault to radio and TV, it is used for preventing malfunction of sensor and measuring instruments

This part reduces noise generated at the output of the inverter (It is possible to use for both input and output)

Running motors with the inverter generates vibration greater than that with commercial power supply This part installed between the inverter and motor reduces torque ripple When the cable length between the inverter and motor is long (10m or more), a countermeasure for a malfunction of the thermal relay by harmonic due to switching on inverter is taken by inserting reactor There is the way to use current sensor in stead of thermal relay Sine-wave filter at the output.

5) Connecting power to the control circuit, separating from main power

When the protection circuit of inverter is activated and the electromagnetic contactor on the input supply to the inverter isolates the power supply, the control circuit power supply from the inverter will also switch off and the alarm output signal will not be hold

The power terminals R0 and T0 are designed to allow a supply to go direct to the control circuit and therefore keep the alarm output signal on

In this case, please connect power terminals R0 and T0, to the primary side of the electromagnetic contactor

(Inverter unit side of ACL, EMI filter, on using input ACL, EMI filter)
